Purities of Rare Earth Metals and Oxides:</strong></p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; color: rgb(68, 68, 68); font-family: Arial, Helvetica, sans-serif; font-size: 12px; white-space: normal;"><span style="text-decoration:underline;">Purity on Rare Earth Oxide Basis.</span><br/>In rare earth industry, chemical purities of rare earth oxides and compounds are often presented on rare earth oxide basis (REO basis), i.e., content of a specific rare earth oxide in comparison to total rare earth oxides (TREO) present: REO/TREO. The statement of &quot;CeO<sub>2</sub>&nbsp;&gt; 99%&quot;, often means CeO<sub>2</sub>/TREO &gt; 99%. To obtain its absolute purity of a specific oxide, you can use formula: REO/TREO X Percentage of TREO in the material.</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; color: rgb(68, 68, 68); font-family: Arial, Helvetica, sans-serif; font-size: 12px; white-space: normal;"><span style="text-decoration:underline;">Purity on Rare Earth Metal Basis.</span><br/>In rare earth industry, chemical purities of rare earth metals are often presented on rare earth metal basis (REM basis)), i.e., content of a specific rare earth metal in comparison to total rare earth metals (TREM) present: REM/TREM.

Price Calculation of Rare Earth Compounds.</strong></p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; color: rgb(68, 68, 68); font-family: Arial, Helvetica, sans-serif; font-size: 12px; white-space: normal;">In rare earth industry, a formula is used to calculate the actual prices of rare earth compounds, such as carbonate, hydroxide and chloride: Actual price of rare earth compound = Price of 100% of TREO (Total rare earth oxide) X Percentage of TREO in the compound. For instance, if price of a cerium carbonate [Ce(CO<sub>3</sub>)<sub>3</sub>·xH<sub>2</sub>O] is quoted as TREO: 45%, Price: $7.63/kg X TREO. Thus, the actual price of the Cerium carbonate is $7.60/kg x 45% = $3.42/kg.</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; color: rgb(68, 68, 68); font-family: Arial, Helvetica, sans-serif; font-size: 12px; white-space: normal;"><strong>C.
